[PATCH] net/bonding: fix slave device Rx/Tx offload configuration

[Huisong Li]

Normally, the Rx/Tx offload capability of bonding interface is
the intersection of the capability of all slave devices. And
Rx/Tx offloads configuration of slave device comes from bonding
interface. But now there is a risk that slave device retains its
previous offload configurations which is not within the offload
configurations of bond interface.
